And, the answer for the the question is :
Explanation:
Approximately 2.4 billion people, or approximately one-third of the total population of the globe, make their homes in coastal zones, which are low-lying sections of land next to the sea that stretch up to 60 miles inland. These zones are also large population hubs, and they are home to the majority (75%) of the world’s megacities. Megacities are defined as cities that have a population that is greater than 20 million people.
Coastal zones are areas where land and water meet, and they are some of the most densely populated regions on Earth. With their proximity to oceans, bays, and rivers, these areas have always been attractive to humans, providing them with easy access to water resources and transportation. However, with the rise of global population and the increasing demand for resources, the pressure on coastal zones has also grown significantly. In this article, we will explore the percentage of Earth’s population that lives in coastal zones and the challenges that come with living in these areas.
According to the United Nations, approximately 30% of the world’s population lives in coastal zones. This number is expected to increase in the coming years, as more people move to urban areas and seek access to water resources. In some countries, such as Bangladesh and the Netherlands, the percentage of people living in coastal zones is even higher, reaching up to 80% in some areas.
Living in coastal zones can offer many benefits, such as access to beaches, fishing grounds, and ports. However, it also comes with significant risks, such as flooding, erosion, and storm surges. These risks have been exacerbated in recent years due to climate change, which has led to rising sea levels and more frequent extreme weather events.
Coastal erosion is a particular concern for many coastal communities. This process occurs when waves and currents remove sediment from the shore, causing the beach to recede. In some areas, this can lead to the loss of homes, businesses, and infrastructure. To combat coastal erosion, many communities have implemented measures such as building sea walls or replenishing beaches with sand.
Another challenge that comes with living in coastal zones is the risk of flooding. As sea levels rise, low-lying areas are becoming more vulnerable to storm surges and flooding. This can cause significant damage to homes, businesses, and infrastructure. To address this issue, many communities have implemented flood protection measures such as building levees or elevating buildings.
living in coastal zones can also have social and economic impacts. For example, many coastal communities rely on tourism and fishing as key sources of income. However, these industries are vulnerable to environmental factors such as pollution or overfishing. Additionally, the high demand for coastal properties can lead to gentrification, which can displace long-time residents and change the character of communities.
approximately 30% of the world’s population lives in coastal zones, and this percentage is expected to increase in the coming years. While living in these areas can offer many benefits, it also comes with significant challenges, including coastal erosion, flooding, and social and economic impacts. As the world’s population continues to grow and climate change poses new threats, it will be important for co
